自燃煤层综放工作面停采前为创造撤面条件,顶煤无法回收,工作面支架回撤后,顶煤冒落,当工作面封闭不严或沿空掘巷留设的沿空煤柱裂隙发育煤体破碎时,构成了漏风通道,给采空区丢煤自燃提供了条件,从而极易造成已封闭采空区终采线自然发火,如何迅速判断发火位置,利用有效手段将发火点快速消灭,减少自然发火对矿井的危害和降低防治过程中的材料浪费是矿井主要解决问题。通过对163下04工作面终采线自然发火的研究,总结了一套行之有效的综放面终采线防灭火技术。
Before coal mining face fully mechanized caving mining face to create conditions for the withdrawal, top coal can not be recovered, face support retractable, the top coal rised, when the face of laxity or left along the roadway pillars Fissure development When the coal is broken, the air leakage channel is formed, which provides conditions for spontaneous combustion of coal in the goaf, which can easily cause the final pick-up line in the closed goaf to spontaneously ignite. How to quickly determine the firing position and use effective means to make the ignition point Quickly eliminate, reduce the natural fire damage to the mine and reduce the material waste prevention and control process is the main mine to solve the problem. Through the research on the spontaneous combustion of the final mining line of 163 04 working face, a set of effective fire-extinguishing technology of the terminal mining line of the fully mechanized caving face is summarized.
